IMPROVEMENT IN MACHINES FOR MAKING AXES.

Specification forming part of Letters Patent No. 121,172, dated November21, 1871.

To all whom it may concern:

Be it known that EDWIN F. HURD, formerly of Canton, in the county ofHartford and State of Connecticut, now deceased, did in his lifetimeinvent a certain new and useful Improvement in Machinery for theManufacture of Axes; and that the following is a full, clear, and exactdescription of the same, reference being had to the accompanying drawingmaking a part of this specification, in which- Figure l represents aperspective view of the machinery as arranged for practical operation.Fig. 2 represents a longitudinal vertical section through the anvil ofthe trip-hammer. Fig. 3 represents a transverse vertical section throughthe drop-die and bed-die, showing the form of said dies and the positionof an ax-blank being pressed between them. Fig. 4 represents atransverse vertical section through the drop-arm and bed of the machine,and showing how the former is forced into or through the' ax-blank toform the eye of the ax. Fig. 5 represents an elevation of the drop-dieand bed-die, showing how the partially-completed ax is formed andflattened between them. Fig. 6 represents a transverse vertical section,showing how the drop-die is held to the drop-plate. Fig. 7 represents alongitudinal vertical section through the arm l and its base l', andthrough the bed-plate, to show the ax is driven off of the handle orformer. Fig.

8 represents in perspective a slotting or scoringtool andsupporting-block or anvil, for` scoring the blank for the insertion ofthe steel, or for starting the opening for the eye of the ax orholding-iron.

Similar letters of reference where they occur in the separate iiguresrepresent like parts in the drawing.

The entire machine is represented in Fig. 1, and the details of themachine are represented in Figs. 2 to 8.

Letters Patent of the United States No. 57,142 were granted to EDWIN F.HURD on the 14th of August, 1866, for a machine for making axes, inwhich many of the features of the present application may be foiuid. Thepresent application may be regarded as an improvement on his own formermachine. The machine as patented was designed for making ax-blanks outof two pieces, which were previously shaped under drop-dies and thenwelded together, with a tool or former placed between said pieces toform or to leave an opening out of which to form or shape the eye of theax.

As the present machine is designed for making the ax-blank of a singlepiece of metal, it involves a decided change of devices and dispenseswith much of the intricate operations of the patented machine. Thepresent machine, too, Without being so complicated and expensive as thepatented one, is in reality a double machine, or one in which twoWorkmen at the same time maybe advancing two separateaxes through theseries of operations necessary to put them into finished axes, exceptthe grinding, and without interfering with each other.

To enable others skilled in the art to make and use the invention, Iwill proceed to describe the same with reference to the drawing.

Of the trip-hammers A A and their anvil or die-blocks B B they areduplications of each other, and are the same and for the same purpose asthose described and shown inthe patent above mentioned, viz., to shapeand true the edges or cutting-ends of the axes as well as to flatten andshape the pole or head ends, and they need not be further described.Upon the bed or frame of the machine there is an anvil-die, C, madeadjustable as to height by means of a Wedge, a, underlying it. Upon thisanvil-die the ax-blank b is placed, and by means of a dropdie, D, the axblank is partially shaped or formed, said dies havingin their faces thecounterform given to the blank. This mechanism is seen in Fig. 3. Fromthese dies the partially-formed ax or blank bis taken and placed uponthe bed or rest E, and a tool or punch, F, is placed upon it at thepoint Where the eye of the finished ax is to be. As the platen G ofthemachine, which carries several of the drop-dies, comes down, itsprojecting arm H strikes the top of the tool or punch F and drives itthrough the blank, as shown in Fig. 4.

The blank may be then taken to the anvil-block or die I and laid flatthereon with the tool, punch, or former F still in it, and there it isflattened and shaped on its sides by said under die and a drop-die, J,that is brought down upon it. The drop-die J is secured to its carrier Gby hooked bars c taking into a groove or grooves therein, said hookedbars being adjustable by a slot and set-screw, as at d, as seen in Figs.5 and 6. The ax b, quite formed and complete, but still on thepunch-tool or Jformer F, is taken and placed on the bed E, as seen inFig. 7, and the forked arm K connected to the carrier G comes upon theedge of the ax, each side of the punch F, and drives down and loosensthe ax therefrom. The eye of the ax is nished and smoothed by thereciprocating former e, which is the same as that shown in the patentabove referred to, and need not be specially described here. Upon themachine as now improved there is a scoring or slotting tool, j", securedto and moving up and down With the carrier G, and may have sideprojections i i. This tool may be used for scoring or. slotting theblank for the reception of the steel that is to be Welded to it; and itmay be used for starting the hole through the blank (which hole isafterward shaped into an eye) and prepare it for the after operation ofthe punch F, which is driven through the blank. Under this scoring-toolthe support or ledge E forms a bearing for the axblank. Though thecarrier G is but a single piece it carries the devices in duplicate, sothat an operator standing one on each side of the machine matrT use itfor shaping and forming axes Without interfering with the one on theopposite side ofthe machine. The same bed, frame, and gearing serves forthe double sets of dies and enables double the Work to be done upon themachine.

Having thus fully described the invention of said EDWIN F. HURD, what Iclaim therein as neviT in itx-machines, and desire to be secured byLetters Patent, is-

l. In combination with the carrier G and bed E, the arms H and K, theiirst for driving the punch through the aX-blank and the other forreleasing therblank from the punch, as described.

2. In combination with the carrier G and support E', the scoring orslotting-cutter f, as and for the purpose described.

3. The arrangement upon the same bed and frame, and With a singlecarrier, G, of a series of anvil and of drop-dies, so that an operatoron each side of the machine may at one and the same time put an aX-blankunder the several successive operations to form it into an ax Withoutinterfering With each other, as described.
